Does he really like me, should I go for it?

There's this guy, I've known him for about 3 months now (I'm a junior he's a senior in high school) we started talking more a few weeks ago, and he sends me good morning and good night texts everyday. We usually talk for a couple hours at night too. We've hung ou, t the two of us, twice, watching movies both time. Last time he put his arm around me, he rested his head on mine almost the entire night. I feel like he likes me, but I also feel like he's too good for me... Should I see what happens, or? Do you think he likes me as more than a friend? (Btw, I'm an exchange student in the US, and I've never had a boyfriend)
